Impact of changing storage quota for a course

Our university is in the beginning stages of adopting Canvas. So far, we have not changed the storage quota for any course; the people who have run into the cap so far have been able to identify and remove unneeded files, move video & audio files to more appropriate servers, and optimize what is left.

I'm sure, however, that we will encounter courses where none of these options completely meet the need.

I'm assuming -- but would like to be sure -- that if we increase the storage quota for the course when it is built, it will need to be increased each time the course is copied forward into a new semester. That is not an appealing solution, from my perspective. We try to not set up situations where we are always handling the same exception each term.

If I'm understanding things in the most optimistic light, we can increase the quota for the master course (where the files are actually uploaded). When the master course is copied into the academic shell, the files will appear to be there, but won't actually have moved. We would thus not need to increase the quota in each new course. Is that correct?

Does it follow, then, that the instructor in the academic shell could upload files into that shell, even though it appears to have filled its quota?

To test this I created two blank, totally pure courses. In one I changed the file quota from 500 megs to another number. I also uploaded 10 or so images to the course files and checked to make sure that that they took up part of the quota (3% in this case). Then I imported the contents of Course 1 into Course 2. When I checked the quota in Course 2 the other than 500 number was evident in the quota setting. The image files appear in course files but the storage limit for course 2 is still showing at 0%.
